It's fitting that the state created out of a chain of volcanic islands would be home to the world's largest volcano. Mauna Loa is located on the Big Island of Hawaii and in addition to being the largest, with a summit nearly 13,700 feet high, it is also one of the world's most active. Since 1843, Mauna Loa has erupted 33 times, most recently in 1984. At 60 miles long and 30 miles wide, Mauna Loa, the name of which fittingly means "Long Mountain" in Hawaiian, takes up about half of the Big Island. Its mass also amounts to 85% of all the other Hawaiian Islands combined.
